Startup Financial Model Review
Find the weak spots in your financial model and business plan before the investor does
A financial model review is a rigorous analysis of the financial model and business plan from the investor's perspective. JB Solutions checks assumptions, unit economics, math, and logic, then delivers a ranked list of what needs to be fixed before you go into a round. Turnaround is 5-7 business days; pricing starts from 80,000 KZT.
When you need this
Preparing for an investment round and want a stress-test before meeting the investor
Built the model yourself or with the team and need an independent perspective
The investor asked for a financial model and you want to make sure it holds up under questioning
You have already received a rejection and want to understand where the vulnerability was
Need a second opinion on a business plan before submitting to a bank or a Damu program
What's included
- Report with findings ranked by severity: blockers, significant issues, and recommendations
- Unit economics check: LTV, CAC, contribution margin, break-even point
- Assumption review covering revenue, growth, and conversion
- Runway calculation and funding needs assessment
- Round-readiness assessment: what must be fixed and what is advisable
- Findings walkthrough in a call or meeting
Process
We review the file and context: stage, round type, and investor profile.
We check the math, assumptions, unit economics, scenarios, and runway.
We rank the findings and document the fix required for each blocker.
We explain what to fix, in what order, and why each point matters to an investor.
Pricing
Depends on model complexity and number of blocks. Revisions after the review are scoped and priced separately.
Why startups lose the investor at the model stage
Most pitch rejections are not about the product. An investor asks three questions: where did this number come from, what happens in the pessimistic scenario, and how much money do you actually need to reach break-even. If the model cannot answer, the conversation ends.
Common errors: revenue grows 20% every month with no justification, CAC is calculated only for the first month, runway is not modeled, unit economics show a margin but do not account for semi-fixed costs. An experienced investor spots each of these in the first five minutes.
The review reproduces exactly that scenario: we look at the model through the investor's eyes and tell you where it will not hold up under questioning.
What we check
- Math: formula errors and linkage issues between model blocks
- Assumptions: the basis for revenue, conversion, and growth figures
- Unit economics: LTV, CAC, and contribution margin by product and channel
- Scenario analysis: base, best, and worst cases, and model behavior under a downturn
- Runway: when the money runs out at the current burn rate
- Completeness: taxes, payroll, CAPEX, and working capital
- Logic: consistency between the business plan narrative and the model numbers
When the review is not the right fit
If you do not have a model yet: the Financial Models service is the right starting point. The review works with an existing file.
If the model needs a full rebuild: after the review, the scope of required changes will be clear. If rebuilding from scratch is the better path, we will propose that as a separate engagement.
FAQ
- What do I need to send for the review?
- The model file in Excel or Google Sheets, a brief description of the business, and the goal: a fundraising round, a bank submission, or something else. That is enough to get started.
- Do you fix the errors or just find them?
- We find, describe, and rank them. If you need changes made, that is a separate scope agreed upon after the report.
- How long does the review take?
- 5-7 business days. Expedited turnaround is possible for urgent requests and is discussed separately.
- Does it work for an early-stage model?
- Yes. We review any model, from early back-of-napkin projections to detailed multi-year forecasts. At early stages, validating unit economics and testing the robustness of assumptions is especially important.
- How does a review differ from building a financial model?
- Building: we construct the model from scratch. Review: we assess a model that already exists and tell you what is wrong with it. Faster and less expensive, but requires an existing file.
- Will I receive a detailed report or just a list of comments?
- A structured report: findings ranked by severity, with each issue described along with what is wrong and how to fix it. Plus a walkthrough call to go through the results.
